How do I know if I need the 2025 or 2026 version?

Check the serial number on the underside of your bidet unit. The first four digits show the month and year in MMYY format. If the date code is 0825 or later, you need the 2026 version. If it's before 0825, this 2025 version is correct.

Will this work on an elongated toilet?

No, this is the round bowl version. TUSHY sells a separate elongated replacement set with different dimensions.

Can I use this with other bidet brands?

No, it's designed specifically for TUSHY Wave and Oasis models and won't fit other brands or TUSHY's attachment-style bidets.

Do I need tools to install this?

No, the seat and lid attach using a sliding lock mechanism built into the bidet unit. You unlock, slide the old parts off, and slide the new ones on.

Replacement seat and soft-close lid for TUSHY Wave and Oasis bidet models

Most toilet seats wear out long before the fixture itself does, but replacement parts for electric bidets are harder to find than generic seats. This set solves that problem for one specific product generation, so you can keep using a several-hundred-dollar bidet instead of replacing the whole unit because of a cracked seat or a lid that no longer stays up.

The catch is the compatibility requirement. TUSHY changed dimensions mid-cycle, so ordering the wrong year means a part that won't mount. If you have the serial number handy, it's straightforward; if you don't, you'll need to lift the bidet to find it. Worth doing once to avoid a return.

The details

This is a direct replacement for the toilet seat and lid that ship with TUSHY's electric bidet seats. If your original components are cracked, stained, or no longer closing smoothly, this two-piece set restores the bidet to factory condition.

The seat detaches using a sliding lock mechanism, so swapping parts takes a few minutes without tools. Both pieces are molded to fit round toilet bowls and include the soft-close hinge hardware that keeps the lid from slamming.

Compatibility is model-year specific. TUSHY changed the mounting geometry in mid-2025, so you must check the serial number on your bidet unit before ordering. Serial numbers with a date code of 0825 or later require the 2026 version; date codes before 0825 need this 2025 version. The serial number is printed on the underside of the bidet unit, and the first four digits indicate month and year in MMYY format.

This set works only with TUSHY Wave and Oasis models installed on round bowls. If you have an elongated bowl, you need the elongated version of this replacement set.
